Window seat



Patented Oct. 27, 193i UNITED STATES PATENT OFFICE THOMAS V. AND FLORENZ 0. ALAND, OF TEST VIEW BOROUGH, -.ALLEGHENY COUNTY, PENNSYLVANIA WINDOW SEAT Application filed'May 31, 1930. Serial No. 458,578.

Thislinvention relates to a window seat adapted to be easily attached to and detached from a window sill and casing so as to provide a Convenient device for washing the'outsides of windows.

' The device is'constructed so that it may be used with window casings having an inner and an outer sill, and with casings having sills of different dimensions. The device also has anadjustable clamp at its rear end which fits over and clamps it to ledges of window casings which have different thicknesses.

In the accomp anyingdrawings which illustrate the present preferred embodiment of V our invention V Figure 1 is a bottom plan view of the window seat; Q r Figure2 is a longitudinal section showing the seat applied to a window casing; and 2t- Figure 3 is an end elevation of the seat as viewed from the right of Figure 2.

, Referring more particularly to the accompanying drawings, the window seating device comprises a seat 2 on which one may sitor stand when cleaning the outside of a window. The seat is substantially rectangular in shape and is provided at its rear end with means indicated generally by the reference numeral 3 for clamping the device to a ledge 4 of awindow casing 55. Window casings aregenerally. formed with an inner sill 6 and an outer sill 7 the inner sill generally being formed of wood and the outer sill of stone. 1

The seat 2is supported on the sills by a support indicated generally by the reference numeral 10, which is adjustable longitudinally of the seat so that the device can be adjustedtofit casings of different widths. The support 10 comprises two blocks 11 disposed on opposite sides of the seat and extending longitudinally thereof, and a transverse connecting-member 12. The blocks 11 and the Y transverse member 12 are secured by screws 13 and slide as a unit longitudinally of the device when it is adjusted to fit a casing of a different width. The transverse member 12 is'provided with slots. which fit over the blocks 11 and the blocks and member 12 are fastened together by the screws 13.

The position of-the seat when attachedto a window casing is illustrated in Figure 2. Each of the blocks 11 is recessed to provide an outer step 15 and an inner. step 16, which rest on the outer sill 7 and the inner sill 6 respectively. The inner ends 18 of the blocks 11 fit against the vertical offset 19 of the window casing.

The support 10 is guided in its sliding movement by a rear guide 20 and a front guide 21. These guides extend transversely of the seat and are provided at each end with tongues 22 which fit in grooves 23 formed in the blocks 11. The guide 20 is rigidly fastened to the seat 2 by screws 25, but the guide .21is loosely attached to the seat by bolts 26 and thumb nuts 27. lVhen the thumb nuts 27 are loosened the support 10 may be adjusted longitudinally of the seat, but when the thumb nuts are tightened they clamp the support in. adjusted position. Thus the member 21, in addition to acting as a guide for the support 10, also acts in conjunction with the bolts 26 and nuts 27 to clamp the support in adjusted position.

The clamping action of the guide 21 is illustrated in Figure 3. The guide 21 is so dimensioned that the distance from the top surface of the tongue 22 to the top surface 30 of the guide is less than the distance between the top surface of the groove 23 and the bottom surface 31 of the seat 2. With this construction a slight space 33 is'normally left between the top surface 30 of the guide 21 and the bottom surface 31 of the seat 2. This space is present when the-thumb nuts 27 have been loosened and the support 10 is ready to be adjusted. In this position of the parts the support may be adjusted, the tongues 22 sliding easily in the grooves 23. After the adjustment has been made the wing nuts 27 are tightened, thereby causing a binding of the tongues22 in the grooves 23 which firmly clamps the support 10 in adjusted position.

The window seating attachment isprovided at its rear end with the adjustable clamp 3, by means of which it may be, secured to the inner ledge 4 of the window casingf. A strip is secured to the under surface of the rear end of the seat 2 by bolts 41. c, The bolts 41 project downwardly some distance beyond the strip 40 as'vievved in Figure 2 and extend through a'strip 42 dis posed; transversely of the seat. The boltstl are disposedadj'acent ofipos'it sides" of the seat 2 and extend loosely through-"openings :iorinjediinthegstrip' 42-. Springs are coiled about the bolts 41 thereby eXerting a dovvnuva'rd'force against the strip 42. The strips 42 areforced toward the seat 2 by turning the thumb nuts 45, thereby bringing the strip 42 into clamping engagement vviththe led ge The strip 42 and the bottom ofthe seat ishioning" inaterial for preventing the there is a tendency for the front end ofthe strip 421:0 rotate about its longitudinal axis.
